My P-wave is connected to my PC, which is in my bedroom. I never turn the amp off, and despite the fact that I've covered the blue dome with black tape, plus put some tape around unused jacks, enough light still shines out of the case to nearly read by!

It's too damned bright and the case has to many openings. I've got the case open and the light doesn't seem like it would be to hard to remove, but I don't want to break anything.
